3r²-6-3r=0 i have to use quadratic formula but i dont get how to imput it
yKpoI14uk [10]

Answer:

r = 2

r = -1

Step-by-step explanation:

So first, we need to get this is order of: ax^2 + bx + c

3r^2 - 6 - 3r

3^2 - 3r - 6

the formula is: -b ± √b^2 -4ac/2a

"ax^2 + bx + c" = "3^2 - 3r - 6"

a = 3

b = -3

c = -6

-b ± √b^2 -4ac/2a

-(-3) ± √(-3)^2 -4(3)(-6)/2(3)

3 ± √9 + (-12)(-6)/6

3 ± √9 + (72)/6

3 ± √9 + 72/6

3 ± √81/6

3 ± 9/6

3 - 9/6

-6/6

-1 = r

3 + 9/6

12/6

2 = r

Find cos(1680°) and sin(1680°). Identify the measure of the reference angle.
s344n2d4d5 [400]

Answer:

Reference angle will be 60^{\circ}

cos(1680)=\frac{-1}{2}

sin(1680)=-0.866

Step-by-step explanation:

We have given cos(1680^{\circ})

It can be written as cos(1680^{\circ})=cos(8\pi +240)

As 240° is lie in the third quadrant

And we know that for third quadrant

Reference angle is given by angle-180^{\circ}

So reference angle will be 240^{\circ}-180^{\circ}=60^{\circ}

Now cos(1640)=cos(9\pi +60)=-cos60=\frac{-1}{2}

sin(1640)=cos(9\pi +60)=-sin60=-0.866
